948045-91-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 948045-91-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,8,0,4 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 948045-91:
(8*9)+(7*4)+(6*8)+(5*0)+(4*4)+(3*5)+(2*9)+(1*1)=198
198 % 10 = 8
So 948045-91-8 is a valid CAS Registry Number.
